Deep-Cheep

From the Super Mario Wiki

A Deep-Cheep is a special variety of Cheep-Cheep found in New Super Mario Bros. and New Super Mario Bros. Wii. Unlike regular Cheep-Cheeps, these fish are green and will actively hunt Mario or Luigi down in the underwater levels. Deep-Cheeps will only give up the pursuit after the plumbers swim far enough away.
